Best Quality Vertical 6 Springs Design Absolute Linear Encoder with Digital Readout Dro

Advanced Optical Measuring System

Principal of Absolute Linear Scale

The grating scale of absolute linear scale consists of two grating masks, they are Absolute Grating Mask and Incremental Grating Mask respectively. Functions of this two masks are as per follows :

Absolute Grating Mask have different mask pattern over the whole grating glass, it gives low resolution but unique position readings over the whole measurement travel.

Incremental Grating Mask is an identical repeatable mask patterns over the whole grating glass, it gives very stable and high quality electronic signal for signal interpolation to achieve very high accuracy and resolution position readings.

Absolute Coding

All absolute coding used in our Absolute Grating Mask are designed by Easson, it is 100% our in-house design and intellectual property, designed and developed for different requirements of applications.

Aging Test

Optical Linear Scale's reader head need to power on for 72 hours aging test before assemble, make sure all linear scale's quality is reliable.

Installation Dimensions

VA10 / VA11 / VA12 / VA13 Series

Connector interface

Absolute linear scale output signal

AS series absolute linear scales offering wide variety choices of output signal interface for different cost, resolution, speed and reliability considerations. Customers can order the most suitable type of output signal interface which optimized to the best of their application and cost requirement.

100% Laser calibration

All glass scale are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
